Gas Discharge Tube Arresters (GDT) are mainly used for protection against electric current, lightning surge and inductive discharge in various communication and electrical power system. With the development of technology, LT800C has become a mature model arrester product in the GDT industry and has a wide application field.

LT800C is suitable for protecting all kinds of transmitting lines from induced overvoltage, direct lightning strikes and so on. It is preferred by many users due to its high reliability, small size, flexibility, easy installation and maintenance, and long-term warranty. The arrester adopts a two-stage design. When the arrester malfunctions, the current generated by the failure will not spread to the system devices of the protected equipment. It is suitable for most communication and power distribution networks, such as long-distance communication links, television power supply lines, railway traction power documents, etc.

The working principle of the LT800C arrester is quite simple. It works like a switch which is based on two basic concepts: current switching and voltage switching. When the voltage of the line exceeds the certain value or when current transmission is too high, the arrester will quickly activate and block the surge from further adhering to the system equipment. Before the system equipment receives the surge, the arrester turns on and interrupts the current. The arrester will return to its inactive state after the current is blocked, thus allowing the system equipment to resume normal operation. The arrester will work again once the voltage exceeds the certain value and the high surge current appears again.

In summary, the LT800C product is one of the most widely used GDT products and can be applied to many systems. It effectively protects the equipment of the system from damage caused by direct lightning strikes and induced overvoltage. Its two-stage design ensures that the system equipment will not be affected by the current generated by the fault. The product is reliable, simple to install, and has a long-term warranty.
